Estudio geotécnico in Gualba

In Gualba, the predominant substrate is composed of granite, gneiss and other igneous rocks, which gives the ground a high bearing capacity and favours shallow direct surface foundations on rock. In specific areas, secondary deposits of compact gravels and sands may be found, as well as sandstones, conglomerates and flysch, together with small areas of slates or schists, although these occupy a limited proportion of the municipality. Normally, the formations present are of low to very low permeability, so water infiltration is scarce and aquifers tend to occur at shallow levels, if they exist.

Seismicity in Gualba is very low, with only seven recorded events over thirty years and a maximum magnitude of 2.9, which removes the need to adopt specific seismic measures in structural design. As the substrate is non-clayey, the risks associated with soil expansivity are ruled out. Therefore, the main constraint for geotechnical studies in the municipality will be the presence of sound rock available for foundation, and the targeted assessment of less competent sedimentary layers.
